Thanks tosca. Made more today but this time to freeze as I needed to use up the very many courgettes I have and couldn't find a reliable one for bottling I must say it took half the time, but freezer space is a a premium right now. I make a lot of soup to see us through the winter months, OH is a big soup fan
My impression is that there are no really satisfactory recipes for canning soups. The best way to do it according to Trillium, who used to provide lots of canning and other advice on this site, is to can the soup with the vegetables in smallish chunks rather than pre-blended. You then blend when you want to serve it. The reason for this is that the temperature at the centre of a thick soup doesn't get high enough to ensure food safety. Unfortunately, courgettes also apparently look a bit unappetising after the canning time required.
Thanks for all your advice LotuSeed. I still haven't given up on the idea of canning.
Soup can be canned lol but it has to be done in a pressure canner. When people start out they are excited at the idea of being able to can their own recipes that they can use right out of the jar. Unfortunately that is not the reality and it can be very discouraging. (Courgettes, other squashes, eggplant and even potatoes are not canned in purée or mashed form because the density of the product can prevent the contents of the jar from heating up properly and killing bacteria.). I canned potatoes this year by cutting them into large, uniform chunks and processing them in the pressure canner. When they were put into the jars they were hard, I did heat them for a few minutes before putting thrm into jars, but after 45 minutes in the canner they were soft, still held their shape perfectly though. I would imagine courgettes or eggplant would turn to mush and that would keep it from heating properly . If you run out of room in your freezer and have a dehydrator you could dehydrate the low acid items you wanted to keep for later use.
The best advice I've found is to keep it simple. If you want to can soup, bottle the broth/stock itself separately, be it vegetable, beef or chicken. Or bottle the beef with broth and the chicken with broth. Bottle (freeze or dry)the low acid vegetables separately as well. It seems like a ton of extra work, but by doing it that way you have a soup base that can be used for just about anything and veggies that can too.
